Passing multiple graphs to sub vi

Hello,
I'm rather new to labview and could use some advice. My current project utilizes a for loop to create a graph for the I-V measurements of each sample solar cell (each plot is on a seperate graph). Multiplexing is done externally via labview control. I have a subvi to show a sample report to the user before they are prompted to save the report.
What would be the best way to pass the data for 6 (or more) graphs to a subvi, and then create the graphs again in the subvi? I think an option would be to utilize a shift register to concate the arrays from each run. Unfortunately, the array size is determined by the user at run-time (number of test points on the graph) and I'm not sure if I can seperate the data properly in the subvi.
Another question would be can I create an array of the seperate graphs (graph 1 in array element 1, etc.) utilizing the data cluster of each graph as an array element? I ask this because it seems that data seperation within the subvi would be easier with this method.
Thanks in advance for the help.
Solved!
Go to Solution.

Without seeing the rest of your code you can use either an array of references or just an array of waveforms. If you data for the graphs is not in the form of waveforms then you can simply create the waveform data type using the Build Waveform function. See attached example for the references approach.

Do you know of an example which shows placing clusters within an array?
I don't understand what you're asking here. Are you referring to making an array of clusters? On the front panel or on the block diagram as a constant, or on the block diagram in terms of building an array of clusters programmatically. For the front panel just place an array control, and then drag a cluster control inside the array. Then place the elements of the cluster inside the cluster element. For a block diagram constant it's the same approach. For building it programmatically use Bundle or Bundle by Name and then Build Array or Replace Array Subset depending on whether you're building a new array or replacing an array element.
Have you done the LabVIEW tutorials? To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

Passing multiple values to the QUERY BDOC parameter?

hi All,
Below is my Query BDOC Anchor Before Query Execute even handler... I'm trying to pass multiple values to the         bq.Z_PartnerFunction query parameter... i.e.
PARTNER_FCT in( '00000012','ZDIVMGR','ZAREADR')
is it possible without creating new Query Bdoc ?
====================================
Private Sub aempchoicewinTCWSearchTAnchor_beforeQueryExecute(ByRef bq As BusinessQuery, ByRef cancel As Boolean)
If Not bq Is Nothing Then
        If sWcDummy = "Yes" Then
                bq.WcDummy = sWcDummy
        End If
        bq.Z_PartnerFunction = "00000012"
        If ctrlZ_Territory.Value <> "" Then
             bq.PRNB_TerrID = "*" & ctrlZ_Territory.Value
        End If
End If
End Sub
================================
Thanks in advance

Hi,
it looks that you already enhanced the query BDoc because you have a new query parameter bq.Z_PartnerFunction, right?
To which BDoc parameter is this BQ parameter mapped? And how looks the related where clause?
For a single filter normally a "=" operator is used. Therefore your example with "in" won't work.
If these three partner functions are fixed then you might hardcoded them directly in the where clause (supposed the BDoc is not used somewhere else where you don't want to have this filter).
Or you might add 3 new BDoc parameters, add 3 new where clauses using a disjunction for them (and using an embracing bracket). In this case always all these 3 BQ parameters need to be filled (or all stay empty) to avoid a SQL syntax error.

Passing multiple parameters (caption and textbox) to another form failing to pick up Caption

I have an Microsoft Access application that is more like a form than a database. Users complete the form and then submit it to us for review. There are many questions and memo fields on the different forms (sections). Some of the memo forms are small due
to the limitation of the size of the form (22 inches) therefore there is a lot of scrolling. I want to include a button on each question so that when users click on it will display a form where I pass the label caption (question) and the answer to this form.
Alternatively I can have a expanded form for each question but that would require over 50 forms. The Application is quite large. I wanted to have one form and just call the different questions/answers.
The below is working for the text box (AnswerTxt). However the CaptionTxt is not holding it's value when it gets to the new form. It's only displaying the name of the variable name, CaptionTxt
On the form where the data resides I have:
Private Sub test_Click()
Dim CaptionTxt As String
Dim AnswerTxt As String
CaptionTxt = Me.lblSect11_5.Caption
AnswerTxt = Me.Section11_5.Value
Debug.Print CaptionTxt
Debug.Print AnswerTxt
DoCmd.OpenForm "Form1", OpenArgs:="CaptionTxt|" & AnswerTxt
End Sub
On the new form with an expanded memo field
Private Sub Form_Load()
Dim intPos As Integer
Dim strControlName As String
Dim strValue As String
If Len(Me.OpenArgs) > 0 Then
' Position of the pipe
intPos = InStr(Me.OpenArgs, "|")
If intPos > 0 Then
strControlName = Left$(Me.OpenArgs, intPos - 1)
Debug.Print strControlName
strValue = Mid$(Me.OpenArgs, intPos + 1)
Debug.Print strValue
' Retrieve Control Name from the first part of the string
Me.lblText11.Caption = Left$(Me.OpenArgs, intPos - 1)
' strControlName = Left$(Me.OpenArgs, intPos - 1)
' Retrieve Value to Assign from the end of the string
Me.txt_Section11.Value = Mid$(Me.OpenArgs, intPos + 1)
' strValue = Mid$(Me.OpenArgs, intPos + 1)
' Assign the value to the control
' Me(strControlName) = strValue
End If
End If
End Sub

The below is working for the text box (AnswerTxt). However the CaptionTxt is not holding it's value when it gets to the new form. It's only displaying the name of the variable name, CaptionTxt
It will, because you are passing it as a literal string with:
DoCmd.OpenForm "Form1", OpenArgs:="CaptionTxt|" & AnswerTxt
In this "CaptionTxt|" is a literal string, whereas AnswerTxt references the variable. It should be:
DoCmd.OpenForm "Form1", OpenArgs:=CaptionTxt & "|" & AnswerTxt

Passing Multiple Values from Multi Select

Hi,
My requirement is simple. I have created a simple Multi Select Option in parameter form and i want to send multiple selected values from the multi select option (in parameter form) to reports.
eg:
I want to send multiple countries code as input .........'US', 'CA', 'IND', 'UK'
Can i do it in Oracle 6i reports, Thanks in Advance.
Regards,
Asgar

Hi Thanks Again,
For such a nice response. I got the Lexical Where condition properly running but still getting problems in catching the multiple values to be passed from form. just i will give u an insight of wat i have done:
SQL:
SELECT ALL FROM EMPLOYEES &cond_1* -- Working FIne
in my Html Parameter Form i have an Multi Select component (the Problem is here) it is not passing more than i value from the form once i am accessing it from web or running it in paper report. In paper report layout it is not allowing me to select more than one value. but in HTML it is allowing to select multiple values but at the server end (After Parameter Form Trigger) it is giving a single value not multiple values.
In PL/SQL when i checking the length of country_id i m getting it as one.
Here is my SQL code
srw.message(10, LENGTH(:country_id_1));
:cond_1 := 'where country_id = '''|| :country_id_1 ||'''';
This is passing the condition properly to SQL but only with single value but i want to pass multiple values
I am struck in this+_
WHERE CONTRY_COLUMN IN ('USA','UAE') -- This variable you have to pass from you form...
Here as you said you gave multiple selection in your parameter form to generate report. So before generation report just prepare variable like this as it is bold above.
and pass parameter through your runtime form to the report as you pass the normal parameter...liket this i gave you example...
ADD_PARAMETER(PARAMETER_LIST_NAME,'P_CONT_PARAM',TEXT_PARAMETER,vString);
Sorry for troubling you for a small thing but please help me to solve this issue.
Thanks Again............

Passing multiple session values from cold fusion into a flash movie

Hello all,
I know that to pass multiple variables into a flash movie
you could use the embed tag like this(with the & between each
variable):
<embed
flashvars="variable1=value1&variable2=value2"
></embed>
Now to pass a single session variable from coldfusion in i
did the following; which worked:
<embed
src="ASdb.swf"
FlashVars="UserName=<cfoutput>#session.userName#</cfoutput>"
width="550" height="400" autostart="true">
</embed>
Note that i had to use the cfoutput tags to get the value
stored in the variables. Now; i tried to do the same thing for two
session variables and the second one does not get read in. Here was
my code:
<embed src="ASdb.swf"
FlashVars="UserName=<cfoutput>#session.userName#</cfoutput>&testTypeID=<cfoutput>#session .testTypeID#</cfoutput>"
width="550" height="400" autostart="true">
</embed>
Can someone please tell me what I am doing wrong? Thank you
very much in advance.

Hold on there was a little error: My final code that did not
work was the following:
<embed src="ASdb.swf"
FlashVars="UserName=<cfoutput>#session.userName#</cfoutput>&testTypeID
=<cfoutput>#session.testTypeID#</cfoutput>"
width="550" height="400" autostart="true">

Passing Multiple Values from a worksheet to PL/SQL function.

Hi All,
Is there any way to pass multiple values selected in a worksheet to a PL/SQL function ?
I will try to explain the scenario:
We have a crosstab report that showing all the customer details, deposit sum of a customer in each date in a date range selected. With the customer details we are showing the Rank of a customer based on the deposit in the latest date selected. Filtering is based on the rank, ie Top50 or Top60 etc.( As I said rank is calculating based on the deposit in the latest date).This is working fine.
Now the new requirement is to : For example, in Top50 report, list all the customers, who were in the Top50 list, in any of the dates selected. We are able to display the daywise rank, but when giving a condition like daywiserank <= 50, the result becomes uncertain. Some blank lines, wrong amounts etc..
As a work around we tried to find out the rank in a PL/SQL function. But the issue there is : we have some multiple value parameters used in the worksheet.
Is there any way to pass multiple values selected in a worksheet to a PL/SQL function ?
Or any other work arounds for the scenario explained?
Reagrds,
Jeneesh

Hi Russ,
Thanks for the response.
Russ Proudman wrote:
1. I thought there was an analytical function similar to rank - or maybe an option of rank - that if there are duplicate records to have them all considered the same rank. So if you had 3 records all the same as rank=2 then a condition saying where rank=2 would return the 3 records. You could check into this.
We are already using DENSE_RANK. But the issue is the output contains incorrect null values nd repeated rows.
We got it solved as I explained in the previous post. But will that AGGREGATION MODE setting ( Which discoverer says - not recommended) have any issue? I mean side effects?
Russ Proudman wrote:
2. Another thought is that you can create a PL/SQL routine - that's called from a SQL function registered in Discoverer - where a table is created that does the first part of your query. Then a worksheet is created to use the data from that table. So, in essence, the table would have your top50 ranked customers. Then you can write any kind of worksheet against that table. However, DBAs are loath to allow tables - that they didn't create! - many times in a PROD environment.
Here also the same problem will occur: as the top 50 will depend upon the parameters. I cannot pass those parameters to PL/SQL Function.And storing the top50 ( itmay be top100 or to 150 also) for all combinations of the parameters is impossible
Russ Proudman wrote:
3. Finally, are you sure you're rank function is correct in that if you're getting blank lines, maybe the 'over' part is not considering all columns needed to determine the rank?
Yes the query we are using is correct. The output QUERY of discoverer gives correct results in Sqlplus.

How to pass multiple values from master to child report

Hello,
How would I pass multiple prompts from the master to child report? So for example, say I want to pass a 'Country' value along with a 'City' value
Would it be?
="<a href=\"../../opendoc/openDocument.jsp?iDocID=ASQlgCemIOlEid1HHUlzyPs&sDocName=DocTest&sIDType=CUID&sType=wid&sWindow=Same&lsSCountry="+[Country]+"&lsSCity="+[City]+"\</a>"
Thanks,
Carter

Carter,
what is the syntax for this?
It is exactly how you have posted in your original note.
"&lsSCountry="+[Country]+"&lsSCity="[City]
This will work providing the target report has a prompt called "Country" and another prompt called "City". Note that your prompt and what you pass between the &lsS and the equal (=) must match exactly, otherwise OpenDocument will not communicate the prompt title to InfoView properly and InfoView will stop and execute the prompt to get the info it needs before running the report. Have you tried what you've posted originally to see if it executes without a problem?
Thanks,
John

How to pass multiple values from workbook to planning function ?

Any way to pass Multiple Values for a single Label in the Parameter?

I have a Report that Contains 2 Parameters, @Customer & @Area. When trying to set up the Available Values for @Area, I'm having issues using multiple values for one Label, i.e. = "4006" Or "4610"
One of the Filters in the Report is an Operation number, which is the [OPERATION] field, which is setup as a filter on the Tablix referencing the @Area parameter.
PROBLEM: I cannot retrieve any data when trying to use the ‘Or’ Operator here. If I simply put “4006” or “4610” I retrieve data, but when trying to combine it returns no data.
Example, I need to allow a user to select ‘Chassis Incoming’, which would include data from Operations 4006 & 4610.
QUESTION:
Any way to pass Multiple Values for a single Label in the Parameter?
I realize the typical solution may be to use ‘Multi-Value’ selection, but in this case we want the User to select the Area and the multiple values for Filtering will be automatically determined for them. Otherwise, they are subject to not getting
it correct.
I have tried several different ways, such as =”4006” Or “4610”, =(“4006”, “4610”), = In(“4006”, “4610”), etc….
Note: We are using Report Builder 3.0

Based on my experience, there's no way to 'intercept' the query that gets passed back to SQL Server, so a Split wouldn't work.
Try creating either a function or stored procedure using the code below (compliments to
http://www.dotnetspider.com/resources/4680-Parse-comma-separated-string-SQL.aspx) to parse the string:
CREATE FUNCTION dbo.Parse(@Array VARCHAR(1000), @Separator VARCHAR(10))
RETURNS @ResultTable TABLE (ParseValue VARCHAR(100))AS
BEGIN
DECLARE @SeparatorPosition INT
DECLARE @ArrayValue VARCHAR(1000)
SET @Array = @Array + @Separator
WHILE PATINDEX('%' + @Separator + '%' , @Array) <> 0
BEGIN
SELECT @SeparatorPosition = PATINDEX('%' + @Separator + '%', @Array)
SELECT @ArrayValue = LEFT(@Array, @SeparatorPosition - 1)
INSERT @ResultTable VALUES (CAST(@ArrayValue AS VARCHAR))
SELECT @Array = STUFF(@Array, 1, @SeparatorPosition, '')
END
RETURN
END
Once created you can do things like this:
SELECT * FROM Parse('John,Bill,David,Thomas', ',')
SELECT * FROM (SELECT 'John' AS TestName union select 'David' AS TestName) AS Main
WHERE TestName IN (SELECT ParseValue FROM dbo.Parse('John,Bill,David,Thomas', ','))
This is what your SQL query would probably look like:
SELECT OperationID, OperationName FROM dbo.Operations
WHERE AreaID IN (SELECT ParseValue FROM dbo.Parse(@Area, ','))
You may need to fiddle around with the Separator depending on whether SQL Server inserts a space between the comma and next value.

How can i pass multiple values by a single variable to EXECUTE IMMEDIATE

Hi All,
I want to pass multiple values for where condition for execute immediate. Something Like this:-
bold
Declare
v_cond varchar(1000);
Begin
v_cond := '''INR','USD'''; --(OPTION 1)
v_cond := 'INR,USD'; --(OPTION 2)
EXECUTE IMMEDIATE 'Delete from table where colm in (:v_cond)' using v_cond;
END;
bold
I am using this into a procedure
Now option 1 gives an error ie a syntax error (; expected or something like that)(I am sorry, i can't tell the exact error here as i am not in the office right now)
and option 2 makes the procedure execute but obviously doesn't delete the records, as it takes the whole as one.
Please Help

How to bind/pass multiple input parameters to sql query in BPEL Process

Hi,
I have a requirement to invoke a query on a database table to fetch the records based on the few input values or bind variables?
I have created a Partner link using the DBAdapter service and have used custom SQL, how can i bind and pass multiple bind/input parameters for these queries.
foreg: if i have to query employee records based on name , desgination and age, these three params would be my input parameter that i will pass when i invoke the BPEL process, bow how can i pass these parameters to the partner link using DBADAPTER service.
Please help
Regards

If the parameter-value is not known beforehand and cannot be determined based on the process instance data at that time, there are 2 options. Either invoke the PL/SQL procedure you named using a DB adapter service to get the value and pass it to the other DB adapter service. Or create a single service (e.g. PL/SQL procedure) that determines the parameter value, executes the query and returns the result. However, this is more a design issue. Does it makes sense to combine these actions in a separate service and use it or are these actions not related? You furthermore state that additional (DB adapter) services make the process heavier. Do you have strict requirements on the time process-instances may run or other such requirements? If not, I think the design-choice on whether combining these actions in a single service should have more priority.

Passing multiple select value from BI publisher to PL/SQL functions

Hi - I have designed a report which pass parameters (Multi select) into a function to get the output result. When a single parameter value is passed to the function, report is being displayed. When multi select value is passed to the function it is returning the error `wrong number or types of arguments in call to 'F_PROCESS_WAVE_DATA'. When i checked the parameters passed to the function, i can see each multi select value is treated as different value and is assigned to different parameter in the function.
Any help on passing the multi select parameter into function will be helpful.
Regards,
Vikram.

All - Issue was resolved. I followed the following steps to resolve the issue
1. Create a PL/SQL table type variable as VARCHAR2 in the database - Say as Larray
2. Create PL/SQL type record and table for the record in database. Lrec, Ltable
3. In BI report pass multiple select LOV variable as Larray(variable).
4. In DB function, Parameter should be defined as LARRAY.
5. Return PL/SQL table type Ltable from the function.

Passing multiple character values from parameter form to PL/SQL

Hi,
I am passing multiple character values from parametr form into
the report query and a PL/SQL procedure. It works fine with the
query, when I use &variable. But, it doesn't compile in PL/SQL,
so I just used the :variable, but not getting any records in the
PL/SQL procedure. Any suggestions?
sincerely,

gj / Fedro,
Only using the &referecne, you can pas a string / multiple character values and this would work for query only.

Passing multiple values to a parameter in report

Can anyone help me how to pass multiple parameters to a parameter in my report.
As user is able to select multiple values from list of values , can I pass the selected values to calling function.
Suppose if User selects Value1,Value2,Value3 from list of values of a parameter P_Org,
I need to pass all these values to parameter P_Org in my Before Trigger Function in Discoverer reproting tool.
Thanks in advance

I have a Before trigger Function to which the parameters will be passed.
Suppose if User selects multiple values for a parameter then how to pass these multiple Values to that parameter?
eg:In first Workbook Before Trigger is fired and the paramters for the trigger are
'par1','par2','par3' etc.
If User selects multiple values for a parameter 'par1' from the list of values displayed then how to pass all these values to 'par1' in Function?
After firing the trigger rows are inserted in a temp_table .My second Workbook will
fetch the rows inserted in this Temp Table.
I hope u understood what my requirement is...
